Zusammenfassung:The present invention relates to a process for producing a metal-matrix composite of significant CTE between the hard base-metal and the soft matrix. The process includes the steps of sintering, pressing and enforced infiltration of the metal-matrix composite compact acting wherein the process is driven by differential thermal expansion coefficients between shell and core materials.
